The Orioles have announced that they’ve acquired infielders Kelly Johnson and Michael Almanzar from the Red Sox for infielders Jemile Weeks and Ivan De Jesus. This is the Orioles’ second significant trade of the evening, having also recently acquired outfielder Alejandro De Aza from the White Sox. The Johnson deal gives the Orioles a bit of low-cost infield depth.

Johnson, 32, began the season with the Yankees, then headed to Boston in a trade for Stephen Drew. (He also played for the Rays in 2013 and the Blue Jays in 2011 and 2012, meaning that he’s now been or will be on the roster of all five AL East teams, with no non-AL East teams in between.) He’s played mostly third base and first base since 2012, and he’s hit .212/.290/.354 for the season. With the Orioles, he’ll likely play mostly at third base in the wake of the team’s loss of Manny Machado for the rest of the year.

The Orioles selected Almanzar from the Red Sox in the Rule 5 Draft last winter, but returned him in early July. Since then, he’s hit .280/.360/.427 in 186 plate appearances for Double-A Portland, mostly playing third base. At 23, he’s the youngest player in the deal.

Weeks was a first-round draft pick by the Athletics in 2008, and they sent him to Baltimore in 2013 in the Jim Johnson trade. The 27-year-old Weeks played in 215 games with the A’s in 2011 and 2012 but has spent most of the past two seasons in the minors. This season, he’s hit .278/.391/.385 in 254 plate appearances for Triple-A Norfolk. Despite the high on-base percentage, the second baseman probably profiles mostly as depth at this point, although CSNNE.com’s Sean McAdam tweets that Weeks will join the Red Sox’ big-league team. (Dustin Pedroia may have suffered a concussion in Saturday’s game, but the timing of Weeks’ acquisition appears to be a coincidence.)

De Jesus, who heads back to the Red Sox after spending a few months in the organization in 2012, also appears to be mostly a depth player. De Jesus came to Boston from the Dodgers in the Adrian Gonzalez / Carl Crawford / Josh Beckett blockbuster, then headed to Pittsburgh almost immediately as the Red Sox traded for Joel Hanrahan and Brock Holt. The Pirates showed little interest in him despite a strong offensive season in Triple-A in 2013, and he signed with the Orioles after the season. The 27-year-old hit .282/.358/.389 in 469 plate appearances for Norfolk this year, mostly playing shortstop.
